Often we lose focus. We begin the race by wanting to succeed in the path of our choice. But soon enough, self-dobt takes over. We see others running their races on their identified tracks and strangely, we believe that they are more right than us. And thence we start running the race on their tracks !
What is the way out of this bewilderment, asks the doubter ?? I would say believe in Euthymia.
Euthymia (Greek) is about being on your own path with happiness without getting distracted by all the others that intersect it. Win you must by reaching the destination. But that without being bothered about beating anyone else to the winning post on their tracks.
Try it even now...never too late. Identify your race, run at your pace and reach your destination without having to bother to win against others on their tracks.
It is about happiness. It's about your race,your track, your measurements.
